USB-interface
Over the USB interface if necessary a software update can be made. For this a consultation with our
V-STE support department for control systems-ventilation technology is necessary.
For communication with a PC (Virtual COMM Port) we make the necessary programs available on
request.
Danger due to electric current
Plug the jumper J1
to both PINs only for a software update via USB interface. The device will not
switch on if this jumper is plugged to both PINs!
Do not replug the jumper under voltage, observe the safety instructions!

Potential at control voltage connections
The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts
are potential free). There is a potential separation between the control voltage connections and the
protective earth. It must be ensured that the maximum external voltage at the control voltage
connections cannot exceed 50 V (between
“
GND
”
terminals and
“
PE
”
protective earth). If necessary, a
connection to the protective earth potential can be established, install bridge between
“
GND
”
terminal
and the
“
PE
”
connection (terminal for screening).

Bypass circuit
Please observe the following during bypass switching (controller shunt with mains voltage):
•
Mutual locking of mains contactor and bypass protection
•
Time delay of at least 1 second during switching
•
The controller
“
enable
”
(ON / OFF) must be simultaneously opened together with cut-off of the
protection on the controller output; during connection it must be simultaneously closed again. For
this a programming is necessary (
IO Setup Enable ON / OFF).
•
By switching OFF necessary waiting period before renewed switching on amounts minimum
90 seconds! (
connection suggestion for bypass with the required time-delay)
•
Never apply line voltage to the inverter output!

Manual Bypass-Switch type S-D-25 and S-D-50
As accessories are manual main switches with bypass function available.
By switching OFF Frequency inverters necessary waiting period before renewed switching on
amounts minimum 90 seconds!
